Vodacom does not want to tell me the remaining balance of my phone contract.

I called Vodacom customer care and enquired about the outstanding balance of my phone contract. The consultant said that I must call the accounts department on ***. When I called them I was referred to consultant after consultant without being helped. I have the right to know the outstanding balance as I am paying the phone contract account. I have never skipped a payment but Vodacom does not want to tell me what my outstanding balance is, instead of doing that they ask me unnecessary questions and tell me unnecessary things for over an hour. Are they not supposed to write the remaining balance on the receipt or statement like other businesses do? Why am I supposed to be tortured when I want to know my outstanding balance? Why does Vodacom disregard my consumer rights? But when it's time to pay they send me reminders. This is not fair at all.
